Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to a main structure of a remote control junction box. Background Technology

[0002] Power control equipment is the core device in a power system for realizing power distribution, control, and protection, and is widely used in power generation, transmission, distribution, and consumption. It encompasses various types, including circuit breakers, contactors, relays, and PLC controllers, and achieves circuit on / off control and fault protection by monitoring parameters such as current and voltage. Remote control junction boxes are key components in industrial automation for realizing remote power control and signal transmission, mainly used for centralized management and intelligent monitoring of distributed equipment. However, existing junction boxes still have certain problems in use:

[0003] For example, a low-voltage control junction box fixing mechanism with application number 201320671769.7 has the following technical solution: it includes two hanging posts horizontally set on a connecting plate. Two hanging slots are provided on one side of the low-voltage control junction box. The two hanging slots have openings for hanging the hanging posts on the side of the low-voltage control junction box near the edge of the low-voltage control junction box. The distance between the two openings is greater than the distance between the two hanging posts. The distance between the adjacent ends of the two hanging slots is less than the distance between the two hanging posts. A telescopic spring is also provided in one hanging slot near the other hanging slot. However, for scenarios that require frequent plugging and unplugging, the existing junction box leads to an increase in the error rate of remote control signal transmission, making it difficult to meet the requirements of high-precision control. On the other hand, the overall sealing of the junction box is not ideal, which may cause corrosion of the internal terminals.

[0004] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0005] To address the aforementioned issues, an innovative design was implemented based on the existing junction box. Utility Model Content
